I believe I heard Laura Ingraham had also debunked this fake news claim
Yeah, they trot this out every time there is a shooting. Leftwing technique is just to fling accusations and hope that some will stick. Most people will hear them and believe them. Any retractions are too little too late (and buried on the back inside pages or mumbled one time in the least watched newscast of the day).
Post it everywhere you can.
Check Laura Loomer post - shows clear picture of shooter
